Buffer after tonestack...what are the results?

[dschwartz]

Hi all.. i´m designing an amp, and for simplicity on channel switching, i would like to have the buffer after the tonestack..i mean, the tonestack will be between the 4th stage and the buffer.. i´m sure i´ve seen that kind of configuration somewhere, but i can´t remember where..

it probably changes the response of the tonestack due to different impedances..but it´s okay to do that? will it sound bad or harm the tubes?

greetings!
